Hm, das heisst da ein bisschen anders :-)

mit /usr/sbin/mknfsmnt legt man einen nfs mount an, der dann mittel
mount gemounted wird.

Nö :-)

Aber mountd(8) unter FreeBSD sagte gerade:
-n Allow non-root mount requests to be served. This should only be
        specified if there are clients such as PC's, that require it.
        It will automatically clear the vfs.nfs.nfs_privport sysctl
        flag, which controls if the kernel will accept NFS requests from
        reserved ports only.

Ich denke, das wird es dann wohl tun.

Vielen Dank erstmal, ich geb' Laut wenn ich das getested habe.
